Explanation

 Secretin and cholecystokinin are digestive hormones. They are secreted in duodenum when acidic food enters there. Secretin stimulates release of bicarbonate rich fluid from the pancreas to counteract the acid. CCK stimulates pancreatic enzyme section like amylase and lipase, which aid in breaking down food. It also causes contraction of the gallbladder, which releases bile into the duodenum.
